Answer:
The answer is (H30+) =3,55e-8M and (OH-)=2,82e-7M
Explanation:
We use the formulas:
pH= - log(H30+) and Kwater=(H30+)x(OH-)
pH= - log(H30+) ----< (H30+)= antilog- pH=antilog- 7,45=3,55E-8M
Kwater=(H30+)x(OH-)
(OH-)=Kwater/(H30+)= 1,00e-14/3,55e-8 = 2,82e-7
The periodic table is organized in such a way that they provide a great deal of information about elements and how they are related to each other.
Explanation:
The periodic table is used for better understanding of patterns and relationships between elements. With the elements arranged in the periodic table allow us to make synthetic elements.
This periodic table helped scientist to discover the elements that are needed for humans to survive. For example plants and animals need elements to grow and chlorine helps animals to digest food and in humans iron helps to carry oxygen around body and chlorine that convert the sun energy to food.
It provides information about elements and how they are related to each other in easy method. They are used to predict the properties of elements.
Thus, the Changes in periodic table is from the creation of new chemical elements and it helps the society in various applications that are used in mining, engineering and other occupations.
Transitional elements are usually described as elements of the d block. oxygen is not in the d block, and hence is not a transitional element.
